This is your credit balance. Even if you are an anonymous user, you are given
some credits to spend. Every IP address has its own account and it is provided with free credits that can be
used to pay for Online Domain Tools services. Moreover, credit balance is reset every day. This is why we call
them Daily Credits. Registered users have higher Daily Credits amounts and can even increase them by purchasing
subscriptions.

Besides Daily Credits, all accounts, including IP address accounts of anonymous
users, have their credit Wallet. Wallet credits are not reset on a daily basis, but they are only spent when a
user has not enough Daily Credits. Registered users can buy credits to their wallets. All IP address accounts
are created with an initial Wallet balance of
3.00. Once IP address account spends
credits from its Wallet, it can not be charged again. This should allow new users to try most of Online Domain
Tools services without registration.

The table in Checkout section clearly summarizes prices that are associated with options you choose
in the tool's form.

Your credit balance is displayed on the right side above the main menu. Even if you are an anonymous user,

Nmap Online Scanner supports most of the functionality of Nmap Security
Scanner. It can be used as a simple and fast port scanner. It can be used
to get information about services that run on a computer in your network.
Using Nmap Online Scanner you can discover running machines in your network
and detect which operating system they are running on. It is also useful
for testing firewall configurations. There are simply too many ways to use
the Nmap scanner and the Nmap Online Scanner tool. This is why you should
check the before-mentioned links to the documentation of Nmap, especially
if it is the first time you are about to use Nmap Security Scanner or Nmap
Online Scanner.

All questions related to the Nmap scanner should be sent to the authors of
the Nmap scanner,
not to the provider of Nmap Online Scanner.
Similarly, all questions related to Nmap Online Scanner (i.e. this service
and its interface) should be directed to the provider of Nmap Online
Scanner, not to the authors of the Nmap scanner.

Nmap Security Scanner is a very complex tool and this is why there are
three different modes in Nmap Online Scanner. The first two modes are easy
to use even for Nmap beginners. The Quick scan of your computer
quickly scans the most known ports and gives you quick information about
the ports and services accessible on your computer from the Internet. The
Full Nmap scan of your computer is a mode in which Nmap Online
Scanner scans a full range of ports that are specified within this option.
This scan can take a while especially if you want to scan more than 10000
ports. The third mode is the Custom scan
mode, which puts
the whole power of the Nmap scanner into your hands. Although there are
some limitations for security reasons, if your intentions are
good you should be able to use the Nmap scanner for whatever you need. In
the Custom mode you specify the arguments for the Nmap scanner yourself,
similarly to what you would do if you were about to run Nmap Security
Scanner from the command line shell.

The most common Nmap modes firstly try to use the host discovery feature
and continue only if they detect that the target host is online. Many
hosts, however, do not respond to ping requests and hence the required scan
itself is not performed. In such a case the only result you get on the
output is that the host seems to be down. If you are sure the host is up
and you are only interested in the scan results and not the information
about whether or not it responds to ping requests, we recommend you to use
-Pn option right away. In case of Quick scan and
Full Nmap scan modes it is not possible to add custom options,
but by selecting one of these scanning modes the Custom scan
arguments are modified and then you can select the Custom scan mode and add
-Pn to the custom arguments.

The results will appear in your browser once they are ready. This can take some time,
however. You can wait for the results with your browser opened or you can enable the
Send email notification when the scan results are ready option.
This option requires you to be a registered user and logged in before you start the scan.
Once the results are ready, the notification will be sent to your email. You will receive
a link to a web page containing your results. If you are logged in, you can also check your
account's Tasks History any time later to
see results of all scans you executed.

Using the Time limit option, you can specify the maximum amount
of time that your scan may take. The default value is 30 minutes and the cost for this time limit
is included in the Basic price. You can set a higher limit up to 120 minutes for your task,
but you will be charged for every extra 5 minutes over the default limit. Note that your
final cost is counted from the actual execution time of your scan. At first, we debit your
account with as many credits as it is needed to cover the maximal limit you set. Then after
the task is completed we credit back unused credits if any. For example, if you have enough
credits in your account, you can safely set the limit to 120 minutes, and if the actual scan
takes only 43 minutes, you will be returned unused credits so that your final cost will be
as if you set the limit to 45 minutes.

If you are interested in processing the output of your Nmap scan with a script or another tool,
you can try to enable a special option Use structured (XML/JSON) output (useful for parsing exports).
This will cause Nmap scanner to be started with additional -oX - parameter sequence,
which produces XML output instead of the standard text output. Then you can either work with the output
as you see it in your browser, or you can export the result to XML, JSON, or TXT format. To do this,
use the blue Get Export icon. Note that if you choose JSON format of export, the XML output produced
by Nmap scanner will be converted to JSON.

You can scan IP addresses in the C class subnet of your IP only. For
example, if your IP address is 89.176.14.234, you can scan addresses from
89.176.14.0 to 89.176.14.255. The only allowed syntax to specify IP address
is a.b.c.d or a.b.c.d-e.

The Custom scan options can have up to 200 characters. For security
reasons, the following Nmap options are disabled:
